I will say pretty much exactly what I said to you via PM, and we'll see what other people think.
Here's the warning you were given:
Don't post content lacking posts or memberate.
As a post, "Reported for pointlessness" lacks content, in that it in no way contributes to the thread. This is against the rules in Flat Earth Debate:
Trolling and low-content posting will not be tolerated and this forum will be moderated quite strictly. "Low-content posting" refers to short posts like "lol" or "yeah" or "that's dumb." Before you make a post in here, ask yourself, "am I really adding anything to the conversation?" If the answer is "no", you probably shouldn't make the post.
I have warned you about this before, so you have no excuse for breaking this rule again. Furthermore, you then decided to argue with the moderator about the warning, something which you have also been warned about before. So let's sum it up:
1) You broke a rule, one which you have previously been warned about. In itself, this warrants a ban.
2) You were warned yet again, and then decided to dispute that warn outside S&C, something which is against the rules and which you have been warned about before. Again, in itself this warrants a ban.
That's my assessment of the situation, and had you started a thread in S&C in the first place, this would have been discussed in an open and transparent manner, without unnecessarily derailing a thread in Flat Earth Debate. Moreover you would not have been banned.
